Abstract

IN THE PRESENT WORK, THE MODEL OF VIBRATION OF GOLD NANO- BEAM INDUCED BY LASER PULSE HEATING IS DEVELOPED IN THE CONTEXT OF TWO-TEMPERATURE GENERALIZED THERMOELASTICITY AND NON-FOURIER HEAT CONDUCTION. THE ANALYTIC SOLUTION HAS BEEN DERIVED IN THE LAPLACE TRANSFORM DOMAIN. THE INVERSE LAPLACE TRANSFORM HAS BEEN CALCULATED NUMERICALLY AND THE NUMERICAL RESULTS HAVE BEEN PRESENTED GRAPHICALLY IN TWO AND THREE DIMENSIONS FIGURES WITH SOME COMPARISONS TO STAND ON THE EFFECTS OF THE TWO-TEMPERATURE PARAMETER AND THE LASER PULSE PARAMETERS ON ALL THE STUDYING FIELDS AND WHICH ONE OF THAT PARAMETERS PLAYS A VITAL ROLE IN THE DAMPING OF THE ENERGY WHICH HAS BEEN GENERATED INSIDE THE BEAM.
